SECTION FOR GENERATORS.

SPECIFICATION forming part of Letters Patent No. 643,926, dated February20, 1900.

Application filed January 2, 1897. Renewed December 18, 1899. Serial.No. 740,822. (No model.)

and has for its object the production of a section which is simple inconstruction, is economically and readily manufactured, handled, stored,and shipped, and is practical and elfective in operation; and to thisend the invention consists in the combination, construction, andarrangement of thecomponent parts of the section, as hereinafter fullydescribed, and pointed outin the claims.

In describing this invention reference is had to the accompanyingdrawings, forming part of this specification, in which like lettersindicate corresponding parts in all the views.

Figures 1 and 2 are respectively front and rear isometric views of myimproved section, a portion of the section being broken away in Fig. 2and Fig. 3isahorizontal section taken on line 3 3, Fig. 1, the grate-barbeing indicated by dotted lines.

My improved section A preferably consists of a single casting and isformed with substantially flat front and rear walls a a, having theirupper and lower portions decreased in width toward their top and bottomedges, and with top and bottom walls a a which are generally formedsubstantially continuous or unbroken, extend or curve toward each otherin opposite directions from substantially their central portions a andare united together at the opposite sides a of the section. The upperand lower portions of the rear wall ct are formed with circulatingopenings a and the front wall a is usually formed with openings a whichare alined with the openings a and receive clamping-bolts, (notillustrated,) passed through a number of the sections.

The upper part of the section A is hollow for forming a timid-containing chamber and is provided with passages A,which extend fromfront to rear thereof through its front and rear walls, beneath theupper circulatingopening a, for forming parts of fines. These passagesare usually arranged in horizontal series, are formed of greater heightthan width, and afford a large amount of heatingsurface. Theintermediate and lower parts of the section A are provided with a recessA extending inwardly from the rear face of said section, from front torear thereof, between the passages A and the lower circulating-opening,and said parts are also provided with fire and draft openings A A,arranged one above the other and extending from the recess through thefront wall of the section. The recess A forms the front ends of acombustion-chamber and an ash-pit for permitting the direct applicationof the heat to the superimposed portion of the section, and its oppositeside walls are provided with shoulders a which support a suitablegratebar B, arranged crosswise of the section between said opposite sidewalls, as seen in Fig. 2. The upper wall of the recess A is providedwith transverse corrugations a for forming a crown-sheet having a largeamount of heating-surface, and the lower wall of said recess extends orcurves upwardly toward the opposite ends of said upper wall.

A' watercontaining chamber A of less thickness than the section Aextends from front to rear thereof in front of the upper end of therecess A and partially surrounds the fire-opening A and a secondwater-containing chamber A is arranged at the bottom and side edges ofsaid recess and projects rearwardly beyond the rear face of the chamberA for forming the bottom and sides of the recess. These water-containingchambers add greatly to the efficiency of the section. The portion ofthe front wall of the recess A interposed between the lower edge of thechamber A and the adjacent edge of the chamber A is here shown as formedintegral with the adjacent parts of the section A; but it will beobvious to one skilled in the art that said portion may consist of aseparate plate or plates secured in position to close the lower portionof the recess A The construction and operation of my invention will nowbe readily understood upon reference to the foregoing description andthe accompanying drawings. 7

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The combination with a section for a generator, the same consistingof a single casting provided with circulating-openings in its upper andlower portions, passages extending from front to rear through its frontand rear walls for forming parts of lines, a recess extending from frontto rear of the section from one face thereof and beneath said passagesfor forming an end of a combustion-chamber, a water-containing chamberextending from front to rear of the section from the opposite facethereof, and shoulders provided upon the opposite side walls of therecess at one side of the water-containing chamber; of a gratebararranged crosswise of the section within the recess and having itsopposite ends supported by said shoulders projecting from the oppositeside walls of the recess, substantially as and for the purposedescribed.

2. As an article of manufacture, the hereindescribed section for agenerator, the sauce consisting of a single casting provided withcirculating-openings in the upper and lower portions of its rear wall,passages extending from front to rear through its front and rear wallsfor forming parts of flues, a recess extending inwardly from the rearface of the section beneath the passages for forming the front end of acombustion-chamber, a watercont-aining chamber of less thickness thanthe section arranged in front of the recess, and a secondwater-containing chamber arranged at the bottom and side edges of therecess and projecting rearwardly beyond the first water-containingchamber and communicating therewith, substantially as and for thepurpose set forth.

3. As an article of manufacture, the hereindescribed section for agenerator, the same consisting of a single casting formed with top andbottom walls extending toward each other in opposite directions fromsubstantially their central portions, said section being provided withcirculating-openings in the upper and lower portions of its rear wall,passages extending from front to rear through its front and rear wallfor forming parts of flues, and a recess extending inwardly from therear face of the section beneath said passages for forming the front endof a combustion-chamber, substantially as and for the purpose set forth.

4. As an article of manufacture, the hereindescribed section for agenerator, the same consisting of a single casting formed with top andbottom walls extending toward each other in opposite directions fromsubstantially their central portions, and substantially fiat front andrear walls, the rear wall having circulatin g-openin gs arrangedsubstantially centrally in its upper and lower portions, said sectionbeing provided with passages extending from front to rear beneath theupper circulatingopening through its front and rear walls for formingparts of dues, a recess extending inwardly from the rear face of thesection between said passages and the lower circulating-opening forforming the front ends of a combustion-chamber and an ash-pit, the topwall of said recess being corrugated for forming a corrugatedcrown-sheet, a water-containing chamber of less thickness than thesection arranged in front of the upper end of the recess, a secondwater-containing chamber arranged at the bottom and side edges of thelower end of the recess and projecting rear-wardly beyond the firstwater-containing chamber, fire and draft openings arranged one above theother between said passages and the lower circulating-opening andextending, from the recess through the front face of the section, andshoulders provided upon the opposite side walls of said recess forsupporting a grate-bar, substantially as and for the purpose described.

In testimony whereof I have hereunto signed my name, in the presence oftwo attesting witnesses, at Jersey City, in the county of Hudson, in theState of New Jersey, this 16th day of December, 1896.
